Design methodologies of shop-floor communication protocols based on FDL tools

Abstract

In this work the real-time field bus PROFIBUS for industrial communication networks, is specified with the formal specification language LOTOS and its associated tools. The paper introduces the general characteristics of LOTOS and its related tools, and the main features of PROFIBUS particularly those related with its data link layer. The methodology and data types implemented are explained, with an instance of developed performance tests for the specification. With LOTOS specification of PROFIBUS protocol, FDL based techniques will contribute to achieve more accurate designs and fast prototyping in the field of industrial communications.
